FLOUR BOLTING OR SCALPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 569,211, dated October 13, 1896.

Application filed May 22, 1896. Serial No. 592,641. (No model.)

To all whom, it may OOILUWH.

Be it known that we, ISAIAH C. LANDES and MILTON O. LANDES, citizens of the United States, residing at Yerkes, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Flour Bolting or Scalpin g Machines, of which the following is a specification.

Our invention has relation to an automatic cleaning device for gyratory-motion flour bolting or scalping machines, and in such connection it relates particularly to the general construction and arrangement of a device for such type of machines and for purposes to be hereinafter more fully explained.

The principal objects of our invention are, first, to provide a simple, durable, and eifective automatic device for cleaning the cloth of a gyratory-motion flour bolting or scalping machine, and, second, to provide a machine of the character described with means for periodically agitating in an opposite direction to the gyratory motion imparted to a flour bolting or scalping machine to effectively clean the cloth or sieve in the treatment of flour and separation of the different grades of the same therein.

Our invention, stated in general terms, consists of an automatic cleaning, device especially adapted for a gyratory-motion flour b0lting or scalping machine.

The nature and characteristic features of our invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which Figure 1 is a vertical section through an ordinary gyratory-motion flour-bolting machine, showing our invention in application thereto; and Fig. 2 is a transverse sectional view on the line at 00 of Fig. 1, showing the detail construction of the device of our invention in application to such a machine.

Referring to the drawings, A represents the shell or casing of each section or compartment of a bolting or scalping machine, which is supported in position on pivotal stilts or standards A and A within a framework B.

a is an inlet to the machine.

a is an outlet-spout from each chamber of the series of the machine for the discharge of tailings or separated matter.

a is a cloth or finely-meshed wire sieve in each chamber and separating one from the other. In each chamber is a spiral or concentrically-arranged partition b, terminating at a hub consisting of a cylindrical sleeve 1), which surrounds a similar but flanged sleeve 5 The partition I) divides the interior of each chamber into two compartments 0 and 0, wherein fine matter and failings are permitted respectively to percolate or pass through the meshes of the cloth or wire sieve a into another section of a like character and the tailings to pass outward through a spout a Through the hub or sleeve b of the machine extends a vertical shaft cl, surrounded by a sleeve (Z provided with set-screws d and d. On the sleeve (1 at the top and bottom are provided fixed eccentric collars d and d snugly fitting the said sleeve. The upper and lower ends of said shaft are respectively j ournaled to cross-bars A and A of the framework B. At the upper end of said shaft d is provided a counterbalancing-wheel or other suitable device R. At the lower end of said shaft d is mounted a pulley c for the reception of a belt (not shown) for permitting in the rotation thereof through the eccentric collars d and (P, a gyratory motion being imparted to the series of separated chambers of the machine on the pivotal supports A and A thereof and thereby to permit the fine matter to be separated from coarser matter or tailings, which latter pass off through the spouts a of the respective sections, while the fine matter passes through the sieves a and away from the machine by the outlet-spout a at the bottom of the machine.

Having described a machine to which our invention is especially applicable, we will now proceed to point out in such a machine the characteristic features of our invention and advantages incident to the use therein.

to the outer casing or shell A, internally thereof, and provided at the free end of the same with a lug h, forming a weight, and intermediate of the weight and rigid connection of this knocker-arn1 with the casing the same is preferably formed of a flexible material, such as wood or spring metal, whereby in the gymtory motions of the machine by the rotation of the sections thereof through the intervention of the pulley e and eccentric collars d and d the knocker-arm H is periodically vibrated back and forth against the lug G of the said arms g and g to actuate the spiral partition and said induced vibrations distributed over the entire surface of the sieve or silk-separating cloth a to effect the liberation of the fine particles of flour or similar material, as well as the tailings separated therefrom, and to prevent clogging up of the sieve or cloth.

It may be here remarked that the cloth or sieve of each section of the machine is thereby maintained in a cleanly condition and the cloth preserved and rendered eiiective for a longerperiod of time than has heretofore been possible in the use of cleaning devices in connection with such general type of said machines.

Instead of rigidly securing the arm H to the outer casing or shell A the same may be hinged thereto, so that in its vibration it will knock against the partition 1) and shell A. It is obvious also that the arm H may knock against any portion of the support for the sieve or separator-cloth, as well as against the spiral partition, without departing from the spirit of our invention.

Having thus described the nature and objects of our invention, What we claim as new, and desire to secure by Letters Patent, is

In a gyratory bolting or sc'alping machine, a series of sections each provided with a spirally-arranged partition adapted tobe gyrated, a sieve or separating-cloth supported at the base of each section and partition, and an oscillating arm carried by each section and adapted to knock periodically against each of said partitions while the machine is being gyrated to thereby agitate each sieve or separating-cloth, substantially as and for the purposes described.

In testimony whereof we have hereunto set our signatures in the presence of two subscribin witnesses.
